ROCKING CRADLE OR SIMILAR ROCKER.

SPECIFICATION forming part of Letters Patent NO. 603,002, dated April26, 1898.

Application filed July 29, 1397. Serial No 646,278. (No model.)

To all whom it may concern:

Be it known that I, JOHN ALLRED, acitizen of the United States, residingat Rockingham in the county of Richmond and State of North Carolina,have invented certain new and useful Improvements in Rookie g Cradles orSimilar Rockers, of which the following is a full and completespecification, such as will enable those skilled in the art to which itappertains to make and use the same.

This invention relates to baby-rockers; and the object thereof is toprovide an improved automatic apparatus for rocking cradles and similarrockers; and with this and other objects in view the invention consistsin the construction, combination, and arrangement of parts hereinafterdescribed and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which- Figure 1 is aside view of one end of a rocker provided with my improvement, and Fig.2 an end view thereof.

In the drawings forming part of this specification the separate parts ofmy improvement are designated by the same numerals of referencethroughout both the views, and in the practice of my invention I providea cradle or other rocker 5, having a head or end board 6, which isprovided with the usual legs 7, to which is secured the rocker 8.

In constructing my improved rocking apparatus I provide a plate 9, whichis secured to the end plate or board 6 and near the top thereof, and Ialso secure to the top of said end plate or board a strong metal stripor yoke 10, which is carried outwardly and downwardly to form an arm 11,as shown in Fig. 1, and acts in connection with the plate or board 9 tosupport the operative mechanism, which -is of the followingconstruction: Mounted between the plate or board 9 and the depending arm11 of the yoke 10 isashaft 12, on the inner end of which is aspring-drum 13, one end of the spring of which is secured at 14c to theplate 9 and the other end to the shaft 12. Mounted adjacent to the drum13 is a gearwheel 15, which is revoluble on the shaft 12, and secured tosaid shaft is a ratchet-wheel 16, and the gear-wheel 15 is provided witha spring-operated pawl 17, which operates in connection with theratchet-wheel 16, and the spring 18, by which the pawl is held inconnection with said ratchet-wheel, is secured to the gear-wheel 15.

The shaft 12 is provided with a head 19, by which the drum is wound,said head being provided with a ring or handle 20, and below the shaft12 is'a shaft 21, on which is mounted a pinion 22, which operates inconnection with the gear-wheel 15, and the shaft 20 is also providedwith an escapement-wheel 28, and I also provide an escapenlent 24, whichis secured to a transverse lever 25, to each end of which is pivotedaleg 26, each of which is provided with an adjustable extension 27, andsaid legs and said extensions are provided with longitudinal slots 28,through which passes a set-screw 29, by means of which the extensions ofsaid legs may be adjusted thereon, and each of said extensions passesthrough a keeper 30, secured to the rocker 8.

The extensions 27 of the legs 26 are provided with heads 81, and thelever 25, with which the escapement 24 is connected, is mounted on ashaft 32, and connected with one end of the lever 25 is a crank-rod 33,which is connected with a crank-shaft 34, which is mounted in the upperend of the yoke 10, and the lower side of the lever 25 is provided witha semicircular notch or recess 85, through which passes a rod or shaft36, which forms a part of the supporting-frame and also regulates orlimits the movement of the lever 25.

The operation will be readily understood from the foregoing descriptionwhen taken in connection with the accompanying drawings and thefollowing statement thereof.

The spring-drum is first wound up in the usual manner, and when this hasbeen accomplished and the said drum begins to unwind the gear-wheel 15will revolve with the shaft on which the drum is mounted by reason ofthe spring-operated pawl 17, which is mounted on said gear-wheel andwhich operates in connection with the ratchet-wheel 16. The shaft 21will also be revolved by said gearwheel and with it the escapement-wheel23, and the escapement 2t will be operated so as to give the lever 25 anoscillating motion. This movement of the lever 25 will cause the legs 26to move up and down alternately, and the lower ends thereof, or of theextensions 27, will be alternately forced upon the floor and themovement will rock the cradle, as will be readily understood. Thecrank-shaft 34 is also revolved by the crank-rod 33, and the inner endof said shaft may be extended and a fan attachment maybe connectedtherewith, if desired. This movement of the parts will be continueduntil the spring-drum is unwound, and, as will be understood, the saiddrum may be wound up as often as necessary or whenever desired.

My improved automatic rocking device for,

cradles is simple in construction and operation and perfectly adapted toaccomplish the result for which it is intended, and it is evident thatchanges in and modifications of the construction herein described may bemade without departing from the spirit of my invention or sacrificingits advantages.

Having fully described my invention, 1 claim as new and desire to secureby Letters Patent 1. In a mechanism for rocking cradles orother'rockers, the combination with a plate and a yoke adapted to besecured to the cradle or other rocker, of a revolublc shaft mounted insaid plate and said yoke, a spring the ends of which are securedrespectively to said shaft, and to said plate, a ratchet wheel rigidlymounted on said shaft, a gear-wheel loosely mounted on said shaft, apawl on said gearwheel whereby it may be rotated in one direction onlywith said ratchet, asecond shaft,

of which are secured respectively to said shaft and to said plate, aratchet-wheel rigidly mounted on said shaft, a gear-wheel looselymounted on said shaft, a pawl on said gearwheel, whereby it may berotated in one direction only with said ratchet, a second shaft. apinion mounted thereon, an escapementwheel, a lever, an escapement,whereby in conjunction with said escapement-wheel, said lever isoscillated, legs pivoted to said lever whereby the energy of said springmay be exerted on the fioor to oscillate the entire structure,extensions to said legs, said legs and said extensions being providedwith slots adapted to register, and a set-screw whereby the said legsmay be lengthened or shortened, and the extent of oscillation of saidstructure regulated, substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing witnesses, this 27th day of July,1897.

hi JOHN ALLRED.
